The size of an earthquake is measured on the Ricter scale it can also be measured on the Mercalli scale.
For an example the 2008 earthquake in China was 7.8 on the Rictor scale and in was XI on the Mercalli scale

the earthquake that happened in japan, the earthquake caused a lot of damage then entered the sea that caused a terrifying tsunami.
It caused a huge fire that burned down the wooden (non fire resistant) buildings. The fire caused most of the damage, not the earthquake.
By constructing buildings and structures that are earthquake resistant.
The amount of damage caused by an earthquake can vary depending on factors such as the magnitude of the earthquake, the depth of the earthquake, the distance from populated areas, and the local building codes and construction practices. Earthquakes can result in damage to buildings, infrastructure, and the environment, leading to economic and social impacts.

The Valdivia earthquake, which occurred in Chile in 1960, was the most powerful earthquake ever recorded. It caused widespread damage in the region, including the destruction of buildings, roads, and infrastructure, as well as triggering tsunamis that caused further devastation along the coast. The earthquake also resulted in numerous fatalities and injuries.
The degree to which people feel an earthquake is called its intensity, while the amount of damage it causes is known as its magnitude. Intensity is based on human observations and perception, whereas magnitude is measured by seismographs and represents the energy released by the earthquake.
Earthquake scales that take into consideration the damage caused by an earthquake are known as intensity scales. Examples include the The Modified Mercalli Intensity Scale and the Macroseismic Scale.

The earthquake caused very little damage.

Examples:What was the extent of the damage done to the vehicle? The earthquake has caused a lot of damage.
The earthquake in Japan caused more damage overall than the tsunami. The powerful earthquake triggered the tsunami and also led to widespread destruction of buildings, infrastructure, and loss of lives. The tsunami primarily affected coastal areas with devastating flooding and destruction.
Four factors that affect the amount of destruction caused by earthquake vibrations include the earthquake's magnitude, which determines the energy released; the depth of the earthquake's focus, as shallower quakes tend to cause more surface damage; the distance from populated areas, where closer proximity results in greater destruction; and the local geological conditions, such as soil type and building structures, which can amplify vibrations and influence the level of damage.
